壳聚糖铈配合物微粒在苹果汁生产的应用研究

Resins of Chitosan-Ce^(4+) Complexes Application in Apple Juice Production

用壳聚糖和铈离子制备出配合物球状树脂(CCGR)有较好的酸碱及热稳定性。通过直接添加CCGR混合振荡和过CCGR层析柱方式应用于苹果汁的澄清,结果发现用CCGR层析柱方式处理后的苹果汁透光率可达96%以上,除Vc有所减少和氨基酸含量有所增加外,其他有效成分含量变化不大。将CCGR应用于生产,结果发现CCGR既有澄清作用,又有脱有机磷农药的效果。

Resins of chitosan-Ce^4＋ complexes （CCGR） are prepared by using the suspending connecting method in the adverse phase. The CCGR has characteristic of stability for acid, alkali and thermal conditions. The CCGR was used to clarification of apple juice by the ways of vibrator and chromatography column, then nutrimental ingredient and transparency of the juice were measured. The results show that clarification of the both ways for apple juice was very good, the ratio of transparency was more than 96%, and the content of nutrimental ingredient, such as amino adds, increased evidently in the apple juice by the CCGR column. The CCGR was used in apple juice factory. Results from the factory show that the CCGR had both clarification and reducing residual of organophosphorous pesticides for the apple juice.
